POWER-OPERATED DRUM OR WINCH APPARATUS- SPECIFICATION forming part of Letters Patent No. 774, ;49, dated November 8, 1904. Application filed March 5, 1903. 'Serial No. 146,266. (No model.)

To all whom it may concern.-

Be it known that I, ALMoN E. NORRIS, a citizen of the United States, residing at Cambridge, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Power-Operated Drum or Winch Apparatus, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

The object of my invention is to provide an improved compact drum or winch apparatus for winding and unwinding cables.

My invention is particularly applicable to an apparatus designed for use in swinging a derrick, wherein the motor speed should be maintained sufficiently high to permit of ready and complete control and by operating through suitable reduction-gears upon the winch or drum produce a relatively slow swinging movement of the derrick.

Furthermore, my invention aims to provide novel friction holding means to enable the derrick when necessary to give or yield sufliciently to avoid damageas,for instance, when a load carried thereby is suddenly diverted or moved to one-side against the power of the motor tending to hold it or move it in an opposite direction.

To enable my invention to be understood, 1 will describe the same in connection with the best embodiment thereof known to me, it being understood, however, that my invention is not restricted to the embodiment illustrated.

In the accompanying drawings, Figure 1 is a side elevation of an apparatus, illustrating one embodiment of my invention. Fig. El -is a top or plan view of the apparatus shown in Fig. 1. Fig. 3 is a vertical cross-section on the dotted line 3 3, Fig. 2. Fig. 4 is a vertical longitudinal section on the dotted line 4 4, Fig. 2; Fig. 5, a horizontal section through the throttle-valve; and Fig. 6, a vertical section of the valve, Fig. 5.

1n the particular embodiment of my invention selected for illustration herein and. shown in the drawings, A is the bed, of suitable shape and construction to carry the various parts of the apparatus. Upon this bed, as herein shown, are mounted at opposite sides and at one end the cylinders C C of the engines, which are herein employed for furnishing the power with which to operate the apparatus. These cylinders contain pistons mounted upon the piston-rods 0, carrying cross heads 0, which reciprocate upon the bar-guides 0 suitably mounted upon the bed. The wrist-pins c of the cross-headsare connected by usual connecting-rods 0* with the crank-pins 0" on usual cranks 0, fast upon the engine crankshaft 0 mounted to' rotate in suitable bearings upon the bed. Eccentrics 0 fast upon the crank-shaft, operate through suitable eccentric-rods c to actuate the Valves within the steam-chests O, and since the engines are reversed by the throttlevalve, but a single eecentric is required for each engine.

Fast upon the crank-shaft c is a spur-pinion cZ, which meshes with and drives a large spur-gear (2, fast upon the winch-shaft (Z journaled in suitable bearings upon the bed.

Loosely sleeved upon the winch-shaft (Z is the winding drum or winch D, herein shown as a winch, about which the operating-cable k is wound. At one of its ends the winch D (see Figs. 3 and 4) carries the diametrically: arranged studs (Z upon which are loosely mounted the toothed wheels (Zfl which at their inner adjacent sides mesh with a common spurgear (Z fast on the winch-shaft (Z and at their outer sides said gears 61* mesh with a common internal gear (Z formed upon or at the inner flange-face of a friction member 6, loosely mounted upon the winch shaft (Z Encircling the flanged member a is a frictionband E, (see Figs. 2, 3, and 4,) said band having its ends oppositely extended and crossed at the under side of said flanged member and secured in suitable manner, as by thenuts a, threaded thereon and seated against suitablyform'ed portions of the bed-plate. Obviously any attempt to rotate the flanged member 6 in either direction will tend to wrap the friction-band E about and upon it, andthereby lock the said flanged member frictionally against'rotation. With said flanged member 6 so held rotation of the winch-shaft [Z by the engine in either direction will operate,through the gears 6Z5 (Z and the internal gear (Z which severally constitute an embodiment of the well known planetary gear, to rotate the winch D in the same direction, but at a greatly reduced speed,the speed reduction depending, of course, upon the ratio of gearing. WVith the cable 7r: connected with and to swing a derrick it is evident that operation of the engine in one or the other direction will thus operate to swing the derrick slowly always in a corresponding direction.

The apparatus is self-contained-that is, the winch speed-reducing and friction holding mechanism or device are arranged wholly within the limits required for the double engine which operates the same.

Referring now to Figs. 5 and 6, I will describe the preferred form of means for reversing the engine. Live steam is admitted through the pipe 0, and the exhaust is discharged from the pipe 0. Between the livesteam inlet and the exhaust the valve-casting O is provided at each of its opposite-sides with two outlets, with which are connected, respectively,the pipes and 0 leading to the steamchest of the engine-cylinder at that particular side of the valve. Each engine is provided with a usual piston or other valve device of well-known construction, whereby when steam is admitted, say, at the ends of the valve the engine will operate in one direction, and when admitted, say, at the middle of the valve the engine will operate in a reverse direction. Consequently one of these pipes, as 0 leads to the outside or ends of the valve and the other, as 0 to the inside or middle of the valve, so that if steam be admitted through the pipes to the respective cylinders the engines will operate in one direction, and if steam be admitted through pipes 0 to the same cylinders the engines will operate in a reverse direction, the live steam and exhaust in each case entering and leaving through the pipes 0 and 0. The throttle-handle 0 is mounted upon the end of the throttle-valve stem 0 which latter within the valve-casting is slotted diametrically to receive the rectangular lugs 12 of two of the oppositely-facing D-valves 1). Referring particularly to Fig. 5, the exhaust-port at each side of the valve-casing is arranged between the live-steam ports in and miwhich latter are connected, respectively, with the pipes 0 and 0 so that as the throttle-valve stem is turned in one or the other direction it will cause its D-valves p to be positioned to admit live steam to one of the ports as or m and place the other of said ports in communication with the exhaust, and the particular ports to or {1: and pipes 0 and 0 through which live steam is admitted, determine, of course, the direction of operation of the engine. Thus the engineer by a single throttle-lever may start and stop the engine, determine its direction of movement and its rate of speed, thereby simplifying the operation of machines of this type. The derrick when swinging may be quickly stopped by reversal of the engine,

the frictionally-held member a yielding sufficiently to take up any shock, which might otherwise prove detrimental. In the throttle the valves p are free to move radially in the holding-slot of the throttle-stem, thus permitting the steam-pressure within the throttle-casing to maintain the said valves tightly pressed against their respective seats precisely as with the ordinary slide-valve of a steam-engine. This eliminates all the difficulties, of which the sticking of the valve is one, which result from the use of a valve in the form of a taper core. With the construction here shown the valve always operates easily, yet remains under all conditions perfectly tight-in fact, it wears itself to a tight fit.

Claims to the features of novelty of my improved valve herein described are embodied in my application, Serial No. 228,253, pending concurrently herewith.

My invention is not restricted to the specific embodiment thereof here shown and described, but may be varied within the spirit and scope of the invention.
